Hi i am from Bulgria , but it is like my country was an ex russian republic . I Have few russian razors and hones .
Both razors and hones are amazing cuters , diferent from the others but very good. I have few - 15 hones, from 400 to 3000 grit . they all are pretty fast cuters and have very uniform gritt size and cratch patern. They are 2 type - aluminium oxide and sic hones , all very hard , working well with oil or soap leather , ferouciouly fast with watter , but they clug and need rubbing for relising the steel dirt.
I have 400 600 800 1000 grit and one that is 3000 -4000 grit very hard and a slow cutter , especialy made for razors . The same one used with oil lather or soap and less presure leaves finer grit marcs , but worcks slowly . All grit scratch patern is observed under 30 and under 60 magnification and theese numbers are compared to Makita1200 / King deluxe1200 / and Chosera 1000 and Suehiro 1000 3000 .
The remarcable thing is that theese russian synthetycs give such uniform scratch patern and are pretty hard that gives such big diferents when used with slurry and watter or oil/lather as 3rd option.
Last weec i bought fram local flea market weel from an industrial grade grinding/polishing masine for 2 $. The size is 38sm diameter with20 sm diameter center hole ,1 sm thick.I sett the bevel on 1 razor wett and it is hard aluminium oxide weel ,the bond is strong ceramic like. Leaves the same as Chosera 1000 grit scratch patern on watter ,and finer that1200 King deluxe when used with slicky dish washing soap.
Just have to cut it to convinient size and they will be 4 or 5 big size stones for setteng the bevel.
Russian abrasives are finest qualitty hard industrial grade hones ,with hight potential.
If fomeone have beenusing rusian or bulgarian hone / ZAi signed/ is wellcome to reply and share
Rusian stropping pastes from crox /green /and diamond pastes areamazing and very productive ,als0 .I have been truyng rusian Goi paste/тонкая/ fine-3-9 microns and it is very fast.
Russians have verry good fine natural hones ,hard,novaculite like -Belorrechitt green Iashma and Ural Iashma/jasper / . They are verry hard and are usualy used as a finishers ,even in conbination of diamond pastes.
We are waitting russian members now to share.
